I forgot to mention that there is no such thing as a 1906/24 Swiss. The "24" designation was an error started by Fred Datig based on incorrect information provided to him by a Swiss source that he thought to be authoritive. The production of the 1906 Waffenfabrik Bern actually began in 1918. You pointed out this discrepancy when you indicated that the gun was produced around the middle of 1923!
